M/Y Halcyon CHT-2608-014 · 8–15 Aug 2026 · Antibes to Portofino

A charter is a dated sequence, not a to-do list. Every item below carries the deadline the MYBA standard implies, counted back from embarkation, so the file tells you what is late rather than waiting to be asked.

Enquiries carry the two numbers that decide whether they are worth working: what the charter is worth, and how many days until the client’s dates make it impossible.

What this is

A concept build, put together in one evening, to show what a charter back office looks like when the charter workflow drives the design rather than a generic CRM being bent to fit it. It is a front end with fabricated data. There is no database behind it.

What it is built from

Every deadline, percentage and document in the booking file comes from the published MYBA charter standard, which is an industry process, not any one company’s property:

  • Eight-page agreement, four signatories: charterer, owner, broker, stakeholder.
  • Clauses 26 to 29, added 2025: KYC, GDPR, confidentiality, sanctions.
  • 50% on signature, balance plus VAT plus APA plus delivery around 30 days before embarkation.
  • APA at 25 to 35% of the fee for sail, 35 to 40% for motor, reconciled after the charter.
  • Preference sheet out 4 to 6 weeks ahead, because the galley provisions against it.

No third-party code, markup or design was copied to build this. Nothing was taken from any existing platform. Typefaces are Newsreader and IBM Plex, both self-hosted under the SIL Open Font Licence.

The one idea worth stealing

Existing tools present a booking as a flat checklist with optional due dates. But a charter is a dated sequence counted back from embarkation, and almost every deadline is derivable rather than typed in. Give the system the embarkation date, the fee and the hull type, and it can calculate when the balance is due, what the APA should be, when the preference sheet has to go out and when the sanctions re-screen expires.

That turns the back office from a filing cabinet into something that tells you the APA is two days late and the preference sheet is nineteen. The summary band is doing exactly that: 3 items late is computed, not entered.

What it does not do

It does not replace the listing networks. Availability data, central agency listings and broker-to-broker distribution live with Yachtfolio, Charter Index, Central Yacht Agent and increasingly Ankor, and no back office replaces those. Anything real would have to integrate with them, not compete with them.

How a real one would be built

Supabase for the data, with row-level security scoping every booking to the brokerage that owns it. n8n for the part that actually matters: a scheduled job that walks the derived deadlines each morning and raises the alerts, so the system chases the preference sheet instead of a broker remembering to. Cloudflare Pages for the front end.
